Recent droughts in Europe were the worst in 2,100 years.
Venus
In our solar system, all planets are revolved in the anticlockwise direction. But Venus is the only planet that revolved in the clockwise direction.

The best place in the world to see rainbows is in Hawaii.
If you're an avid rainbow gazer and want to get your fill of the beautiful phenomenon, look no further than the state of Hawaii. A study published by the American Meteorological Society in 2021 noted that the area's "mountains produce sharp gradients in clouds and rainfall, which are key to abundant rainbow sightings." Air pollution, pollen, and a large amount of cresting waves also help to put Hawaii at the top of the list when it comes to rainbow quantity and quality.
Aerogel
What is Aerogel? ‘Aerogel’ is a broad term used to talk about an extraordinary group of materials that have been used since the 1960s in space travel, but are now finding uses across a whole range of industries. ‘Aerogel’ is not a specific mineral or material with a set chemical formula-rather, the term is used to encompass all materials with a specific geometrical structure. This structure is an extremely porous, solid foam, with high connectivity between branched structures of a few nanometres across. Though aerogel is technically a foam, it can take many different shapes and forms. The majority of aerogel is composed of silica, but carbon, iron oxide, organic polymers, semiconductor nanostructures, gold and copper can also form aerogel. However, within the aerogel structure, very little is solid material, with up to 99.8% of the structure consisting of nothing but air. This unique composition gives aerogel an almost ghostly appearance; hence it is often referred to as
Maximum"Oxygen" producer in Earth.
Our atmosphere is made up of roughly 78 per cent nitrogen and 21 per cent oxygen, with various other gases present in small amounts. The vast majority of living organisms on Earth need oxygen to survive, converting it into carbon dioxide as they breathe. Thankfully, plants continually replenish our planet’s oxygen levels through photosynthesis. During this process, carbon dioxide and water are converted into energy, releasing oxygen as a by-product. Covering 5.5 million square kilometres (2.1 million square miles), the Amazon rainforest cycles a significant proportion of the Earth’s oxygen, absorbing large quantities of carbon dioxide at the same time.
The fastest gust of wind ever recorded on Earth was 253 miles per hour.
Hang on to your hats because this isn't your average wind storm. In 1996, a tropical cyclone named Olivia hit off the coast of Barrow Island, Australia with such a force that it broke an incredible record. According to The Weather Channel , "Olivia's eyewall produced five extreme three-second wind gusts, the peak of which was a 253 mph gust," which blew past the previous wind record of 231 mph set in Mount Washington, New Hampshire back in 1934.
Sound in Space
Sound need's a medium to travel. If there is no medium we can not hear the sound. That's why sound can't travel in space. In space, there is no medium.
Alkali metals
Some metals are very reactive that can be reactive with air. These metals are known as alkali metals.
Oxygen in ocean
How much oxygen comes from the ocean? Scientists estimate that 50-80% of the oxygen production on Earth comes from the ocean. The majority of this production is from oceanic plankton — drifting plants, algae, and some bacteria that can photosynthesize. One particular species, Prochlorococcus, is the smallest photosynthetic organism on Earth. But this little bacteria produces up to 20% of the oxygen in our entire biosphere . That’s a higher percentage than all of the tropical rainforests on land combined. It’s important to remember that although the ocean produces at least 50% of the oxygen on Earth, roughly the same amount is consumed by marine life. Like animals on land, marine animals use oxygen to breathe, and both plants and animals use oxygen for cellular respiration. Oxygen is also consumed when dead plants and animals decay in the ocean. Calculating the exact percentage of oxygen produced in the ocean is difficult because the amounts are constantly changing. Scientists
The Smallest guitar
The smallest guitar in the world is of the size of a red blood cell The world's smallest guitar is of the size of a red blood cell. It was developed by scientists from Cornell University.US The nano guitar has six strings each of 50 nano meters wide.When plucked by an atomic force microscope ,the strings would resonate.But it will at be inaudible frequencies. The first of its kind was made in Cornell University in 1997. The nano guitar was made from crystalline silicon.It is about 10 micrometers long .It can be viewed with the help of an electron microscope .
